P-40 drop tank
Lova, there are about a Gazillion things that aren't made for scale planes. That probably includes your drop tank. But don't dispare.. you could build one in a jiffy from blue foam. If you have a picture of it.. draw the top and side outlines on the foam and carve/sand to shape. Afterwards glass it with light cloth. Thats it, you will be rewarded with learing something new AND your drop tank.. try it... you might like it! lol.. Regards BobH.
